Uncomment the following line to install leafmap if needed.

In [1]:

# !pip install leafmap

# !pip install leafmap

In [2]:

import leafmap.deck as leafmap

import leafmap.deck as leafmap

Create an interactive map.

In [3]:

m = leafmap.Map(center=(40, -100), zoom=3)
m

m = leafmap.Map(center=(40, -100), zoom=3) m

Out[3]:

Add basemap.

In [4]:

m = leafmap.Map()
m.add_basemap("HYBRID")
m

m = leafmap.Map() m.add_basemap("HYBRID") m

Out[4]:

Add vector data to the map. It supports any GeoPandas supported format, such as GeoJSON, shapefile, KML.

In [5]:

m = leafmap.Map()
filename = (
    "https://github.com/giswqs/streamlit-geospatial/raw/master/data/us_states.geojson"
)
m.add_vector(filename, random_color_column="STATEFP")
m

m = leafmap.Map() filename = ( "https://github.com/giswqs/streamlit-geospatial/raw/master/data/us_states.geojson" ) m.add_vector(filename, random_color_column="STATEFP") m

Out[5]:

Add a GeoPandas GeoDataFrame to the map.

In [6]:

import geopandas as gpd

import geopandas as gpd

In [7]:

url = (
    "https://github.com/giswqs/streamlit-geospatial/raw/master/data/us_counties.geojson"
)
gdf = gpd.read_file(url)

url = ( "https://github.com/giswqs/streamlit-geospatial/raw/master/data/us_counties.geojson" ) gdf = gpd.read_file(url)

In [8]:

m = leafmap.Map()
m.add_gdf(gdf, random_color_column="STATEFP")
m

m = leafmap.Map() m.add_gdf(gdf, random_color_column="STATEFP") m

Out[8]:

Create a 3D view of the map. Press Ctrl and hold down the left mouse button to rotate the 3D view.

In [9]:

initial_view_state = {
    "latitude": 40,
    "longitude": -100,
    "zoom": 3,
    "pitch": 45,
    "bearing": 10,
}
m = leafmap.Map(initial_view_state=initial_view_state)
filename = (
    "https://github.com/giswqs/streamlit-geospatial/raw/master/data/us_states.geojson"
)
m.add_vector(
    filename,
    random_color_column="STATEFP",
    extruded=True,
    get_elevation="ALAND",
    elevation_scale=0.000001,
)
m

initial_view_state = { "latitude": 40, "longitude": -100, "zoom": 3, "pitch": 45, "bearing": 10, } m = leafmap.Map(initial_view_state=initial_view_state) filename = ( "https://github.com/giswqs/streamlit-geospatial/raw/master/data/us_states.geojson" ) m.add_vector( filename, random_color_column="STATEFP", extruded=True, get_elevation="ALAND", elevation_scale=0.000001, ) m
